グレーザジヤイロ。[Claims for Utility Model Registration] A semiconductor laser that oscillates first and second laser beams, and an optical fiber that converts the first and second laser beams oscillated from the semiconductor laser into parallel beam bundles, respectively. A light transmission means for transmitting and propagating; a half mirror for inputting and combining and interfering with the first and second laser beams after passing through the light transmission means; and a half mirror attached to the half mirror to cause the half mirror to minutely vibrate. It is characterized by comprising a dithering means, and an angular velocity detecting means for detecting the oscillation frequency of the first and second laser beams from the frequency of the beats formed by combining and interfering with the half mirror, and calculating the angular velocity. Ring laser gyroscope.
